Don't announce the puzzle is solved if it was already in a solved state

[jbierema]

This is especially relevant for a puzzle where the solution is not included. If someone completes the puzzle but then realizes a word needs to be changed, every letter that is modified will call up the message that the puzzle is completed, which makes editing multiple letters a tedious process. (Deleting a letter is a workaround of course.)

Thanks! I'll take a look at this.
